摘要
基于公路建设项目后评价理论,对桥梁抗震加固效果持续性评价的主要内容进行探讨,选取时变可靠度和安全剩余使用寿命作为抗震加固持续性评价的评判指标,建立指标成功度的评分准则,提出桥梁抗震加固效果持续性评价的成功度评判方法。分析表明,桥梁抗震加固可持续性评价结论与工程实际相符合,可供同类工程参考。
Based on the theory of highway construction post-evaluation,the main contents of bridge seismic strengthening effect of persistent evaluation are discussed. Time-dependent reliability and remaining life are selected as the persistent evaluation indicators of bridge seismic strengthening effect,and the indicators of score criterion are determined. A set of success-degree evaluation method of persistent evaluation method is established,The results show that the conclusion of the persistent evaluation of bridge seismic strengthening agrees with the practical engineerings,and it can be referred by similar projects.
